程序在将代码段分配到子程序之前工作

Question

这是我在将代码分配到子程序后遇到的错误

"NameError: name 'P1D1' is not defined"

这是代码：

def dice_rolling():
    #stage 2 dice rolling
    #P1D1 means player ones dice one value and so on with P1D2
    import random
    #player ones turn
    print("player ones turn")
    P1D1 = random.randint (1,6)
    print ("your number is ",P1D1)
    P1D2 = random.randint (1,6)
    print ("your second number is",P1D2)
    #player twos turn
    print ("player twos turn")
    P2D1 = random.randint (1,6)
    print ("your number is" , P2D1)
    P2D2 = random .randint (1,6)
    print ("your second number is",P2D2)


def score_calculation():
    round_number = 0
    round_number = round_number + 1
    #player 1 score calculation
    total_P1 = P1D1 + P1D2
    P1_score = P1_score + total_P1
    if total_P1 % 2 == 0:
        P1_score = P1_score + 10
    else:
        P1_score = P1_score + 5
    if P1D1 == P1D2 :
        P1D3 = random.randint (1,6)
        P1_score = P1_score + P1D3

    #player 2 score calculation
    total_P2 = P2D1 + P2D2
    P2_score = P2_score + total_P2
    if total_P2 % 2 == 0:
        P2_score = P2_score + 10
    else:
        P2_score = P2_score + 5
    if P2D1 == P2D2 :
        P2D3 = random.randint (1,6)
        P2_score = P2_score + P2D3
    print("player ones score at the end of round ",round_number, "is" , P1_score)
    print(P2_score)

dice_rolling()
score_calculation()

Answer 1

您在函数 dice_rolling() 中创建变量，然后尝试在 score_calculation() 函数中使用它们。您需要定义全局变量或在 score_calculation() 函数中定义变量，或者您可以将此变量作为参数传递给 score_calculation() 函数

import random


def dice_rolling():
    # P1D1 means player ones dice one value and so on with P1D2
    import random
    # player ones turn
    print("player ones turn")
    P1D1 = random.randint(1, 6)
    print("your number is ", P1D1)
    P1D2 = random.randint(1, 6)
    print("your second number is", P1D2)
    # player twos turn
    print("player twos turn")
    P2D1 = random.randint(1, 6)
    print("your number is", P2D1)
    P2D2 = random.randint(1, 6)
    print("your second number is", P2D2)
    score_calculation(P1D1, P1D2, P2D1, P2D2)


def score_calculation(P1D1, P1D2, P2D1, P2D2):
    round_number = 0
    round_number = round_number + 1
    # player 1 score calculation
    total_P1 = P1D1 + P1D2
    P1_score = total_P1
    if total_P1 % 2 == 0:
        P1_score = P1_score + 10
    else:
        P1_score = P1_score + 5
    if P1D1 == P1D2:
        P1D3 = random.randint(1, 6)
        P1_score = P1_score + P1D3

    # player 2 score calculation
    total_P2 = P2D1 + P2D2
    P2_score = total_P2
    if total_P2 % 2 == 0:
        P2_score = P2_score + 10
    else:
        P2_score = P2_score + 5
    if P2D1 == P2D2:
        P2D3 = random.randint(1, 6)
        P2_score = P2_score + P2D3


    print("player ones score at the end of round ", round_number, "is", P1_score)
    print(P2_score)

dice_rolling()
